Title:
エンジンの過回転防止装置
Document Type and Number:
Japanese Patent JP4923772
Kind Code:
B2
Abstract:
A device and method that suppresses delay in response to gear-shifting in upshifting during control for preventing over-rotation. An engine torque control part (6) controls the torque of the engine (1) based on a driver request (APO) for driving force, a rotation velocity sensor (15) detects the rotation velocity of the engine, and an over-rotation preventing part suppresses the controlled torque based on the velocity and prevents over-rotation of the engine (1). An over-rotation prevention releasing part releases suppression of the torque based on the rotation velocity lowered due to upshifting of the automatic transmission, and an engine torque increasing rate regulating part regulates the increasing rate of the torque when said suppression of the torque is released and the torque is increased. Thus, a sudden increase in engine torque is avoided.
